Hello,

With version 1.0.0.2261 I’ve a this strange problem with transcoder.
the transcoder in optimize video and in streaming web it use all 4 cpu of raspberry pi3 , but on chromecast it use only 1 cpu.

What is the format of the video you are trying to stream?

Look here :

https://support.plex.tv/hc/en-us/articles/201998867-Investigate-Media-Information-and-Formats

to see how to find the information. Just need the info provided by using the “Open the Media Info Window” method.

It may very well be that the Pi needs to be fully transcoded (does not have the proper codecs) and the Chromecast just needs to be remuxed for audio.

With New Transcoder 0.9.14.6 it use all 4 cpu (thread), with 1.0.0.2261 it only one cpu (thread).
It’s strange because in optimize function it use all thread
